Gov’t Strengthens National Preparedness for Floods, Landslides ahead of Rainy Season

The Government has strengthened necessary measures to anticipate potential hydrometeorological disasters as most parts of Indonesia enter the rainy season. Head of the Meteorology, Climatology, and Geophysics Agency (BMKG) Teuku Faisal Fathani reported that the peak of the rainy season is predicted to occur from December 2026 to February 2027.

“The onset of this year’s rainy season has been delayed by 20 to 30 days, with the peak of the rainy season spanning three months: December 2026, January, and February 2027,” stated the Head of BMKG following a limited meeting chaired by President Prabowo Subianto at the Jakarta Presidential Palace on Monday (11/09).

During the meeting, the Government discussed crucial precautions to anticipate floods and landslides triggered by extreme rainfall. BMKG has prepared an early warning system capable of providing weather forecast data down to the sub-district level, ranging from hourly projections to monthly outlooks.

“This enables us to identify which sub-districts across Indonesia are under advisory, warning, or major warning status,” he explained. The information would subsequently be integrated with flood and landslide vulnerability mapping to allow earlier mitigation actions.

In addition to enhancing early warning systems, the Government has prepared weather modification operations in coordination with the National Disaster Management Agency (BNPB), particularly to protect zones still undergoing post-disaster rehabilitation and reconstruction. These operations include directing rainfall toward areas where it poses no significant risks or suppressing rainfall formation over certain locations.

“We are striving to ensure that rainfall does not occur over areas that are not yet prepared. Infrastructure projects currently underway would also be safeguarded from extreme rainfall that potentially triggers further disasters,” he noted.

BMKG has also monitored tropical cyclone activity. Toward the end of 2026, tropical cyclone potential was predominantly concentrated in the Northern Hemisphere, whereas in early 2027, more cyclone activity was expected to come from the south across the equator.

BMKG would continue to provide weather updates to relevant ministries and agencies to strengthen readiness throughout the rainy season.

With the peak of the rainy season approaching, the Government puts public safety, the protection of disaster-prone areas, and the continuity of post-disaster recovery as top national priorities. (BPMI of Presidential Secretariat) (YA/TM)
